  • koyo thrust ball bearing small particle damage caused by noise detection method

    introduction:KOYOBearing in the process of use,Many people focus only on the big questions。I didnt see any minor problems。Often because of these small problems caused by thrust ball bearings[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Damage can even end life。 First, the filtration effect of the air filter is poor or the intake system is not sealed well,To check the intake system each

  • Simulation of forming process of steel plate for car

    introduction: In the rolling process,Due to the influence of various factors,The longitudinal extension of the strip in the roll gap is often unevenly distributed along the width direction。The result of the non-uniform extension along the width leads to the existence of non-uniform longitudinal residual stress in the rolled strip along the width direction,When a certain critical value is exceeded,The strip will produce waves and warping after rolling。 Instability problem of cold rolled wide sheet,Two-dimensional modeling can be carried out according to the form of plane stress,The thickness of the sheet is determined by the shell elementshell63Is described by the real constant。 Artificially cut two ends out of the cold rolled strip

  • Die design

    introduction: Act 1 Plastic formability Plastic is the main component of high molecular weight synthetic resin,Under certain conditions(Such as temperature、Pressure etc)A material that can be molded into a certain shape and retains its shape at room temperature。 The properties of plastics according to the surface after heating,Can be divided into thermosetting plastics and thermoplastic plastics two categories。The former is characterized by a certain temperature,After a certain amount of time heating、After pressurizing or adding hardener,It hardens by chemical reaction。The chemical structure of the hardened plastic changes、Hard texture、Insoluble in solvent、Heat no longer softens,If the temperature is too high

  • Equivalent mass

    introduction:dengxiao zhiliang Equivalent mass equivalent mass An imaginary mass concentrated at a selected point of a mechanical component。The machine is in operation,Its kinetic energy is equal to the sum of all its components。The equivalent moment of inertia is an imaginary moment of inertia given to a member of a machine,In the process of mechanical operation,Its kinetic energy is equal to the sum of the actual kinetic energy of all the components in the machine。The application of this concept can simplify the mechanical dynamics of single-degree-of-freedom mechanisms,That is, the quality of each component、The moment of inertia is reduced to the equivalent component(Equivalent effect)with

  • INA oil-free bearing process problem elimination method

    introduction:INAbearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Allow slight running noise during work,If the noise is too loud or there is abnormal noise or banging,It indicates that the oil-free bearing is faulty。 The reasons for noise generated by rolling bearings are more complex,One is inside the bearing、Outer ring with surface wear。Due to this wear and tear,Break the shaft
